In the Banking section, currently the Bank Transactions tab shows the Upload Source in a way that does not make it clearly obvious that it is clickable or that clicking it would change the source for what is being displayed.
Whilst there is a subtle background highlight, perhaps it is too subtle.
1: Original current interface
2. The underline to indicate a clickable link
3. The box to indicate a clickable button
Perhaps better indicate in some other way which of the sources had been selected and that the other option is clickable to change the upload source.
